Streaming markdown retained growing cache keys and queued obsolete native renders. This bounds iOS measurement-key storage to 8 MiB, keeps only the newest pending render, and combines the common file-link/table preprocessing path while preserving the existing fallback ordering.
Native changes and their source regression harness now live in the maintained enriched-markdown fork. T3 Code consumes the rebuilt 1.2.0-t3.16-558767d9 tarball; no enriched-markdown patch remains. The archive records the exact source commit in t3-fork.json.
Validation: fork install/build passed; the native harness passes against both fork source and the installed tarball, covering byte eviction, oversize keys, LRU updates/removal, latest pending revision, capture release and invalidation. Packed native files match the fork exactly. T3 Code check:changed passes (format, lint, unused patches, knip, affected typechecks and tests). A native client rebuild is required.
Existing benchmark and methodology and fixture matrix describe host measurements, not phone latency or battery improvements. Main-queue apply captures can still accumulate; this does not claim a global two-revision memory bound.
Implemented and verified with GPT-6.1-sol through the T3 Code Codex harness.
Kept the common combined file/table pass and AST-derived pipe fallback; HTML remains separate. Main's file-embed callback path preserves HTML → file links → embeds → tables and makes no JS parse-reduction claim. Native code and its reusable source harness belong in the maintained fork; the local patch, scripts and package test entry were removed by the maintainer follow-up. The concurrent main merge was retained after independent review; no replacement push was needed.
Fresh host report, fixture matrix, reproducible bundle, independent published-head audit: PASS. 63,538 comparisons, zero differences. Combined stream: 81 → 54 parse entries; host median 2,711.054 → 1,406.421 ms; logical UTF-8 stage traffic 1,555,548 → 1,138,401 bytes. Callback stream: 80 → 80 parses; no reliable speedup asserted. These are host observations, not heap or phone measurements. Portable C++ cache recapture: 269,254,656 → 8,388,416 accounted bytes; queue evidence is HOST MODEL ONLY. Independent pass 2 reran 58,964 comparisons with zero differences and verified source applicability to the published braces-only revision.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This PR changes the production iOS markdown renderer by adding byte-budgeted cache eviction and coalesced asynchronous rendering, alongside a broader preprocessing-path refactor. The behavior is well tested and scoped to markdown, but the new native scheduling and rendering semantics warrant human review.

Mobile Markdown rendering now uses a shared pipeline for HTML conversion, inline file links, and table breaks. Compatibility tests compare its output with the prior transformations. The mobile app also points to an updated enriched Markdown tarball.
Changes: Mobile enriched Markdown rendering
| Layer / File(s) | Summary |
|---|---|
Shared Markdown transformations apps/mobile/src/lib/markdownDocument.ts | A shared transformer coordinates inline file-link edits and table-break insertion. applyMarkdownEdits applies edits in source order, and the Markdown helpers delegate to the shared transformer. |
Native rendering integration and compatibility tests apps/mobile/src/native/EnrichedMarkdownText.tsx, apps/mobile/src/lib/markdownInlineFileLinks.test.ts | Native rendering calls markdownForNativeRendering. Tests compare its output with frozen prior transformations across fixture prefixes and newline styles. |
Renderer tarball update apps/mobile/package.json, pnpm-workspace.yaml, apps/mobile/deps/README.md | The dependency source and build allowlist target the updated tarball. The README describes an 8 MiB measurement-key budget and coalesced pending renders. |

Explanation
The description explains the problem, implementation, verification results, limitations, and required rebuild. It does not provide the required triaged issue or explicit maintainer approval for scope, and it does not use the template headings.
Resolution
Add the required ## Problem, ## Change, ## Scope and approval, and ## Verification sections. In ## Scope and approval, link the triaged issue or approval discussion with the explicit maintainer approval comment. If no approval exists, obtain and link it before merging; do not rely only on the Macroscope review requirement. Preserve the detailed verification evidence and limitations.
Comment @coderabbitai help to get the list of available commands.
The authorization source is the maintainer’s direct T3 audit request, quoted and linked in the description. This is maintainer-authored work under @juliusmarminge, not an external contribution seeking approval for an unsolicited direction. There is no public approval discussion to link, and I will not invent one or classify this native scheduling change as a trivial-fix exemption. The description retains that limitation explicitly. Macroscope’s human-review requirement remains applicable before merging; this thread has no merge authorization. No implementation finding was reported.

| 10 | the default dependency path when either mode is supplied, and pass the mode |

| 14 | - Around line 290-357: Update the table-break logic in transformNativeMarkdown |
| 15 | to calculate lineStart from the nearest preceding source newline before |
| 16 | start.offset, handling both carriage returns and line feeds, rather than |
| 17 | deriving it from start.column. Keep the existing prefix matching and edit |
